Set it up as per the instructions...thats how I raced mine the first time, although I used different tires. Buggy was Dialed!
I used the silver sway bar in the rear, and I had to adjust the shims a little bit in one of the tranny's to get the mesh right. Be sure to loctite the threads that the instructions tell you too.
These buggy's run HOT, well any 4wd car does. Gear low, and cut vents in the body. I don't have alloy parts on it yet..was thinking about getting the center bulkhead and shock tower mounts though.
